Cyber security experts are warning companies with online shops to have adequate protection against DDoS attacks in place after a 70% increase in that kind of cyber-attack was recorded on Black Friday.

What Is A DDoS Attack?

A denial-of-service attack is a cyber-attack on that is intended to make a computer or network unavailable to users, and a distributed denial-of-service attack (DDoS) is one that uses multiple compromised systems, sometimes thousands, that are often infected with a Trojan virus to launch a single attack on one system. The sheer number of requests that the target receives (called a ‘flood’) typically overload the resources and memory and render the targeted computer or network unavailable.

Black Friday – 70% Increase!

According to DDoS protection provider Link11, DDoS attacks on e-commerce providers showed an increase of more than 70% compared with other days in November, and Cyber Monday attacks showed a massive increase of 109% compared with the November average.

Up To 100 Gbps

Gbps, which stands for billions of bits per second, is a measure of bandwidth on a digital data transmission, and is the level used to gauge the intensity of DDoS attacks. When you consider that Link 11 have reported that attacks of around 6 Gbps are more than enough to exceed the capacity of most websites, the Black Friday and Cyber Monday recordings of levels of up to 100 Gbps in some attacks were extremely high.

The Cost of DDoS Attacks

Bitkom research found that cyber-attacks can cost retailers an average of €185,000. This total includes costs of IT repair, loss of sales revenue and reputational damage to the business.

Research from Corero, in April this year, found that (DDoS) attacks typically cost enterprises up to £35,000 per attack in lost business and productivity, as well as mitigation costs. The research revealed that 69% of respondents said their organisation experiences anywhere between 20 and 50 DDoS attack attempts a month – about one attack per day! 78% of respondents in the Corero research said that the loss of customer trust and confidence was the most damaging effect on business of DDoS attacks.

Christmas Warning

Based on the huge increase in DDoS attacks on Black Friday and Cyber Monday, cyber security professionals are warning businesses to prepare now in order to protect themselves against an expected high level of DDoS attacks over the Christmas shopping period.

What Does This Mean For Your Business?

Businesses trying to simply expand their own infrastructure to absorb peak loads with their own resources may not have enough resources to stop determined attackers who may decide to deliver ever greater attacks to overwhelm services completely.

One of the best ways that businesses can prepare themselves for a possible increase in DDoS attacks is by investing in scalable, cloud-based protection solutions that can counteract the kind of targeted overloads caused by DDoS attacks.

Making sure that the business has an updated and workable Business Continuity Plan and Disaster Recovery Plan in place are also important elements of preparing for the possibility of the aftermath of a successful DDoS attack.
